In a word: no.  See the attached excerpt from syslog which may explain why.

I have explored a bit into the problem.

1.  It occurs when ./autogen is run an will likely also occur when 
./configure is run ... this is something internal to autogen.

To eliminate the rpmbuild, I ran things from a git repository.

2.  git checkout v1.0.2-maint does *not* have the problem.

3.  git checkout v1.0.3-maint does have the problem

4.  So does git checkout v1.0.3-rc1

One approach to identify this may be to do a binary search through the 
commits.
